In vitro peptide penetration in the stratum corneum (SC) and viable skin (VS) after 4 h. The skin was treated with 0.1 mM FITC-labeled P20 mixed with 1 mM WLR (WLR+P20, also represented in Fig. 1) or 0.1 mM FITC-labeled WLR–P20. The results were reported as means ± SD; the number of replicates was 6 per experimental group. *p < 0.05 compared to WLR+P20.
